.To all whom it may concern: v

Be it known that I, HERMAN S. HEIOHERT, a citizen of the United States, residing at Pittsbur in the county of Allegheny and State of lennsylvania, have invented or discovered certain new and useful Improvements in Apparatus for Teaming Metal, of which improvements the following is a speclficatlon.

Considerable difficulty is experienced in pouring metal from ladles in insuring the deposition of the metal at a given point or along a given line by reason of the movement of the ladle lip or edge over which the metal flows from one vertical plane to another while the ladle is being turned on its pivotal axis. As

a ladle is being tipped its 'ourin lip or edge,

vpassin through an are 0 a one e, will move away our a vertical plane passing through the pivotal center of the ladle until such lip is in a horizontal lane through such-pivotal center. After the lip or edge has reached such horizontal plane a further turning movement of the ladle will cause the lip or edge to move toward the vertical planepassing through the center of movement of the la dle. In practice it is customary to endeavor to compensate for this in-and-out movement of the pouring lip or edge by re lating the flow of metal over the lip or edge ychanging the rate of tip ingmovement of the ladle. This method is, owever, uncertain and unsatisfactory especially when comparatively little metal of metal is not sufficient to produce a rate of flow which will compensate for the inward movement of the pouring lip or edge, and consequently the last ortlons discharged from the ladle will be eposited back. from the given point or line.

The invention described herein has for its object a construction andcombination of-ele- .me'nts whereby the pouring lip or edge can be sition outside or inside of a vertical plane passing through the lip at the beginning of the curing movement.

T e invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part ofthis specification, Figure 1 is a side elevation of my improved ladle-manipulating mechanism shownm connection with a travelthe table and roller be ng omitted.

may be'employed. As shown in the ings, bridge 1- of the crane is provided with remains in the ladle and the head.

ing crane and a bed and roller for s reading glass. Fig. 2 is a front elevation of t e same, Fig. 3 is a detail view of the controllinglever, and Figs. 4, 5, and 6 are diagrammatic views illustrating some of the movements that can be im arted to the ladle.

nthe practice of my invention it-is preferred that the ladle and its manipulating mechanism, to be hereinafter described,

should be carried by an overheadcrane, al-

though any other suitable form of su port suitable guide-rails for the wheels of atrolley; to which is'secured a framework having guide-arms 2 for the liftin -head 3, which is adapted to be raised and lowered by means of a drum 4, carried'bythe trolley and preferably operated by an electric motor 5, theliftinghead being connected to a wire rope passing around t e drum. The lifting-head 3 is provided with bearin s 7 for the reception of the journal-pins 8, om which depend the suspensory bars or rods 9, said bars being provided with eyes at their lower ends for the reception of the trunnions 10 of the yoke 11,

engagin the ladle 12. The trunnions are provide with crankarms 13, which are connected by pitmen 14 to crankarms 15 on a shaft 16, which is adapted to be rotated through suitable gearing by the 1110-.

tor 17. By the rotation of the shaft 16 the yoke 11 and ladle. 12 will be tip ed, the trunnions of the yoke rotating in the at the lower ends of the suspensory bars or rods 9. When shifted by the mechanism thus far described, the pouring-lip a of the ladle will pass through an arc b, as shown in Fig. 1 and it will be observed that the lip a will earings gradually approach a vertical plane tangential to the spreading-roller 18 as the lip moves from normal positlon-to a horizontal plane passing through the axis of the trunnion 10. As the ouring-lip moves on downward it will gradua 1y recede from the roller 18. During the first portion of the movement of the ladle the ti pmg movement can be so regulated that t e metal, as glass, will be deposited immediately in front of the roller; but asthe lip moves from the horizontal plane passing through the trunnions posited farther away and s read. out along the table in front of the ro In-order to prevent this spreading out, suitable means are provided whereby the ladle may be so the metal will be dev shifted independent of its rotation on the axes of the trunnions that the pouring lip or edge a will at the end of the tipping movement be not farther away from the vertical plane tangential to'the roller than at the beginning the movement, but by preference will be closer to such tangential plane at the end of the tipping movement, so a that although the rate of flow of metal from theladle will be slower during the latter portion of the-tip ing movement the metal will be deposite in the same relation to the roller as at the beginning of the tipping movement. A convenient means for effecting this shifting of the ladle consists of a lever 20, havin its fulcrum or pivot pin on the supporting bars or rods 9. One end of these levers is ivotally connected to the pitmen 14, whi e the portion of the lever on the opposite side of the pivotal centers is provided with means for engaging with guidin members ,which in the present instance are ormed by channelbars 21,secured to the frame depending from the trolley. The levers are provided with ins orrollers 22,moving along these channelars as the levers are shifted by the rotation of the shaft 16.

By reference to Figs. 1, 4, 5, and 6 it will be seen that b reason of the en agement of the pins or r0 lers 22 with the c annel-bars the sus ending-bars 9, andwiththem the ladle, wil be, shifted tothe left as the pitmen are raised, turning the levers 20 on'their pivots. By suitably adjusting the length of the lever from its-p1vot center to the point at which the pins or rollers are secured and also by adi'usting the angularity of these portions of the evers to the portions between the ivots and the connections of the levers to t e pitmen any desired back-and-forth swing of the ladle during its tipping movement can be produced. It is preferred that the levers 22 should be made in sections, so that the portion thereof extending toward the channelbars can be adjustedin angular relation to the other portions of the levers. In the construction' shown the levers consist of two sections 20 and 20, the portion 20 being provided with a curvedslot and the portion 2O being adapted ,to swing about the pivot-pin as its center and be secured to the part 22 by a bolt passing through the slot. The ortions 20",with the levers, are also slotted ongitudinally,'so that the pins or rollers in engagement with the channel-guides may be adjusted to different distances from the pivotal centers of the levers. The channel-bars, which serve as guides, are also adjustably mounted, so that when in normal position the ladle may hang naturally from its supporting shafts or trunnions 8, as shown in Fig. 1.

In Fig. 4 is diagrammatically represented the movements of the ladle when the pouring lipor, edge is to move in a vertical straight line. It will be observed that the roller or pin on the lever traveling along the guideway is in a line when the parts are in normal position, passin /through the center of the 'ournals 8 and t e ouring lip or edge a.

owever, the point ,re resentin the pins or rollers on the levers, ies outsi e of a line from the axes of the journals 8 and the pouring-lip a, the latter will move in a plane having a curvature opposite that which the lip or edge a would have if the ladle should turn on its trunnions without any shifting thereof. If the point 1) lies inside of the line from the axes of the journals 8 to the point a, the latter will move through a plane of a reverse curvature of that shown in Figs. 5 and 6.

It will be seen that in'all cases during the first part of the tipping movement of the ladle, when the point a would be normally traveling away from a vertical plane assing through the axes of the trunnions, t en the ladle is shifted to the left an amount equal to the travel under normal conditions, of the oint a from said lane and that during the atter portion of t e tipping movement the ladle will be moved in t e opposite direction,

so as to again compensate for what would be the normal movement of the lip a during the latter portion of the tipping movement.

In Fig. 5 I have diagrammatically shown an arrangement in WhlOll the pouring-lifina will move in the direction of the point or e where the metal is to be deposited and that at the end of the pouring movement the lip a will be a considerable distance to the ri ht of a vertical plane passing through the ip at the begimiing of the pouring movement. In Fig. 6 1s shown an arrangement in which the If, I

lip a will be at the end of the pouring movement, to the left of a vertical plane passing through the lip or edge at the beginnin of the a curved plane in passing between these two positions. I

It will be readily understood by those skilled in the art that in the practice of my invention the position of the ladle is autopouring movement. The lip moves t ough 7 'matically adjusted, so that the metal will be always deposited-when the ladle is tipped uniformly and at a rate proportional to the head of metal in the ladle at the same point or line during the entire po operation.

My improvement is-especia ly applicable for use in connection with the teeming of glass onto a bed or table in the manufacture.

of sheet and wire glass, where it is desired that the metal shall be evenly distributed alon in front of the spreadin -roller in a line para lel or ap roximatelygaraIlel to the axis of the roller and should not e spread out irregularly alonglthe table in front of the roller.
